7. Enter the show ft group detail command in Exec mode to verify the state
of each appliance. Upgrade the ACE that has its Admin context in the
STANDBY_HOT state (ACE-2) first by entering the reload command in
Exec mode. After ACE-2 boots up, it may take a few minutes to reach the
STANDBY_HOT state again. Configuration synchronization is still enabled
and the connections through ACE-1 are still being replicated to ACE-2.
Note Do not add any more commands to the ACE-1 configuration. At this
point in the upgrade procedure, any incremental commands that you
add to the ACE-1 configuration may not be properly synchronized
to the ACE-2 configuration.
host1/Admin# reload
This command will reboot the system
Save configurations for all the contexts. Save? [yes/no]: [yes]
8. Perform a graceful failover of all contexts from ACE-1 to ACE-2 by
entering the ft switchover all command in Exec mode on ACE-1. ACE-2
becomes the new active ACE and assumes mastership of all active
connections with no interruption to existing connections.
host1/Admin# ft switchover all
9. Upgrade ACE-1 by reloading it and verify that ACE-1 enters the
STANDBY_HOT state (may take several minutes) by entering the show ft
group detail command in Exec mode. Because both ACE-1 and ACE-2 are
running the same version of software now, configuration mode is enabled.
The configuration is synchronized from ACE 2 (currently active) to ACE-1.
If ACE-1 is configured with a higher priority and preempt is configured on
the FT group, ACE-1 reasserts mastership after it has received all
configuration and state information from ACE-2, making ACE-2 the new
standby. ACE-1 becomes the active ACE once again.
host1/Admin# reload
This command will reboot the system
Save configurations for all the contexts. Save? [yes/no]: [yes]
10. Enter the show ft group detail command to verify that ACE-1 is in the
ACTIVE state and ACE-2 is in the STANDBY_HOT state.
